STOR'M-SAFJH FASTENER.

Application filed April 21,

To all whom it may concern:

Be it known that I, drnron Sornionnnn, a citizen of the United States, residing at St. Paul, in the county oi Ramsey and State of Minnesota, have invented certain new and useful improvements in Storm-Sash Fastoners, of which the following is a specnieation. I

flhis invention relates to extensions or bowing devices tor storm sash, and has for its object to provide in a device of this class, means for initially applying a powerful pressure against the inside of the sash in the process of opening it, for the purpose of forcing the latter out of its frame when it is frozen shut or swelled by dampness. In the drawings V igure 1 is a side view of a storm sash shown in held openposition by an extension bracket embodying the invention.

Fig. 2 a side view of the extension lever, showing it in three successive positions assumed in the process of opening the sash.

Fig. 3 is a side view of the lever showing it pivotally mounted on the sash and in locked position.

Fig. d is a fragmentary horizontal sectional view through the sash and frame on line et-d of Fig. 3, and I i Fig. 5 is a perspective view. of the invention unattached.

In the accompanying drawings A represents the window frame, B the storm sash adapted to fit snugly into said frame to close the window opening, and (3 suitable hinges whereby the sash is pivotally suspended by its upper rail so as to be swung outwardly.

The invention comprises a window frame bracket D, a sash bracket E and a stay bar F. T he sash bracket, shown, is formed with an outwardly extending lug 1, integral with the base plate 2 and disposed at right angles to the latteigsaid base being provided with suitable screw holes whereby it may be firmly secured to the sash.

The window frame bracket is formed of a plate bent at right angles to form a base 3 having suitable screw holes whereby it may be firmly secured to the inner .t'ace ot the side of said frame, and an upper and lower lug 4-. and 5 respectively extending laterally into the window opening and being vertically spaced edgewise from one another. The'lower edge of the lug Hi adjacent said Specification of Letters Patent. Patented J an, 1921,

space is straight and unbroken throughout ts length, while the upper edge of the lower lug 5 is "formed with an upstanding finger 6 whereby the space between said lugs for a distance from their outer extremities is restricted.

Swingingly mounted on the lug 1 by means of the pivot pin T so as to swing upwardly thereon is the strap-like stay bar ll, the latter being of uniform width and having in the upper edge thereof a notch 9 adapted to receive the lower edge of the lug l, said notch being of adeptli to permit the stay bar to be inserted sidewise through the restricted space between the lugs; may then be moved longitudinally back and "forth between the lugs and swung downwardly against the one of the latter to hold the sash against outward movement, the finger 6 constituting a guard against lateral displacement.

A notch 10 near the free end of the bar and in the lower edge thereof is adapted to rece've the upper edge of the lug 5, whereby the. sash may beheld in open position (Fi 1). At its pivot end the stay bar is hook shaped in form, the pivot 7 being located in the body of the bend of the hook a distance beyond the bottom 11 of the crotch or jaw thereof. The crotch loosely embraces or receives edgewise the edge of thelug 5 when the stay bar is in locked position or in other words is hanging vertically from its pivot (Fig. 3), the lower edge 12 of the bar continuing directly to the bottom 11 of the crotch, and being adapted to contact flatly against the ad] acentfiat face of the lug 5, so that the sash will be held firmly against outward movement. A pin 13 in the window frame is placed so as to enter the notch 9 to lock the depending bar to the sash in the usual way. Extending downwardly and outwardly from the bottom 11 ot the crotch the hook is termed with a curved portion it which may be termed a cam.

ll hen it is desired to open the window, the bar is first released from the pin 13 and then turned upon its pivot, whereby the cam 14 will be caused to roll upon and brace against the outer face Oi? the lug 5, the upper edge of the latter operating as a pivot in the crotch or" the hook to force the sash out of its frame away from the bracket D. Owing to the length of the stay bar a powerful leverage is etl'ected and great pressure may thereby be The bar exerted against the inside ofthe sash to free it from the frame when it is frozen or swelled it requiring no special movement on the part of the operator other than is ordinarily required. In Fig. 2 three successive positionsvassumed by the cam are shown, the pivot 7 having traveled from (Nto b to c, in the initial movement of the stay bar, the V shaped jaw of the hook permitting the bar to be swung upwardly, and the cam 14: bracing against the bracket D to force the pivot forwardly away from the operator.

lVhen the pivot is at c the bar is free to be projected forwardly until the notch 10 engages with lug 5.

I claim:

1. The combination with the window frame and a window sash for said frame hinged at the top thereof so as to swing outwardly and upwardly, of a bracket on the sash. a bracket having an outwardly extending lug on the window frame adjacent said first named bracket when the window is closed, and a stay bar having a notch pivoted on said first named bracket at a point above said lug in a manner to engage with the latter when suspended from its pivot to hold the window closed and to be projected outwardly over said lug to engage the latter with its notch to hold the window open, a portion of said stay bar extending when the sash is in closed position over said. lug and downwardly between the latter and the sash so as to brace against said lug when said bar is initially moved from its suspended position to effect a. leverage against the sash.

2. The combination with the window frame and a window sash for said frame hinged at the top thereof so as to swingout wardly and upwardly, of a bracket on'the window sash, a bracket on the window frame standing lug,

ed to receive said lug to hold the window 7 closed when said bar is in vertical position, the crotch of said V shaped jaw being located so as to pivot on said lug in the initial movement of said bar for the purpose set forth.

8. In a device of the class described the combination with a window frame and a swingable window sash in closed position in said frame, of an outstanding lug on the sash, a stay bar pivoted at its top to said lug and depending therefrom, and a lug extending from the window frame to a position between the bar and sash, said bar be ing pivoted to swing upwardly so as to be projectable outwardly to open the sash and being formed below itspivot with a notch snugly embracing the upper edge of said last named lug when in depending position.

4. In a device of the class described the combination with a window frame and a swingable window sash pivoted at the top of said frame and in closed positionin the latter, a bracket on the sash having an outa vertically disposed stay bar pivoted at its top to said lug so as to swing in a vertical plane, a bracket on said frame having a lug positioned between said sash and bar a distance below the pivot of the latter said bar extending to said last named lug and fitting over the upper edge thereof to effect a pivotal relation during apart of the swinging movement of said bar and sash for the purpose set fortl In testimony whereof I aflix my signature.
